現在開始玩LINUX系統的新手越來越多了,但是Linux對於很多新手來說,還是有那麼一點紙一樣的難度的,在windows系統下,我們可以很方便的查看到機器的硬體的配置和信息,那麼在Linux下面,如何查看硬體信息呢,OK,下面就帶領LINUX菜鳥們如何查看機器的硬體配置和信息,首先是幾個小點心,開開大家的胃口,告訴大家其實有很多命令可以單獨實現你想要知道的硬體信息,如果等不及了,呵呵,可以直接看
的主角命令,哈哈,這裡暫時保密... 1. 顯示主機的體系結構 [root@localhost ~]# arch ##這2個命令都是同樣的功能
i686
[root@localhost ~]# uname -m
i686 2. 顯示內存使用情況 [root@localhost ~]# cat /proc/meminfo

[root@localhost ~]# 3.查看CPU信息 [root@localhost ~]# cat /proc/cpuinfo

00:0f.0 VGA compatible controller: VMware SVGA II Adapter #這是我的虛擬機
[root@localhost ~]# dmesg | grep -i VGA
Console: colour VGA 80x25
[root@localhost ~]#
5. 顯示網卡信息 [root@localhost ~]# lspci | grep -i eth
02:00.0 Ethernet controller: Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE] (rev 10)
6. 顯示硬碟信息 [root@localhost ~]# df

[root@localhost ~]#
哎,好累啊,其實還有許多硬體的信息呢,下面隆重推出本文的主角：一個超級無敵的命令,你可以看到幾乎是一切你想知道的各種硬體配置和詳細的參數,：噹噹當「,下面這個超級無敵的命令就是-------
dmidecode,據說這個命令的內容讀取子BIOS,那是相當的牛X和準確啊,哈哈,前提是你的BIOS沒有被JS動過手腳啊,哈哈... [root@localhost ~]# dmidecode > hardware.txt #由於這個命令的輸出超級多,把他寫入到這個hardware.txt 文件里,你可以在裡面找到你想要的一切...
[root@localhost ~]# vi hardware.txt # dmidecode 2.9
SMBIOS 2.31 present.

哈哈,就舉例到這裡吧,
以這個命令結尾,幾乎可以不看前面的內容了,就這個dmidecode 幾乎可以通吃所有硬體信息了,
我給本文改名叫做」Linux下一個命令通吃硬體信息「哈哈,如果你還不是很熟悉,還不試驗下,當然讀者有更好的方法,記得給我留言,萬分感謝...
